Indian, Cambridge, American and Australian. The Indian route holds CBSE-aligned, NIOS and BOSSE. Your child is not tied to one syllabus on the day they join, and can move to another route later without a fresh admission.
A second subject teacher sits in every lesson beside the class teacher. A child who stops answering is picked up in that period, not at the report card. A class of forty cannot pause for one child. A class of twenty with two teachers can.
Morning, afternoon and evening slots on Indian Standard Time. School fits around a music lesson, football or cricket practice, JEE or NEET coaching, or a parent's shift. Your child keeps the school year and the thing they are serious about.
Tests adapt to your child and progress is tracked as they go, measured against their own earlier work rather than a class rank. There are 7,000+ recorded lessons to go back over and 50+ clubs beside the timetable.
Every grade gets online laboratories alongside a learning kit, so practical science runs through the year instead of once a term.

About Sunbeam World SchoolKolkata families switch for five reasons: a monsoon that does not stop the lessons, hours back from the commute, a pace set to the child, international curricula without an admissions queue, and a school that survives the next posting.
Our timetable ran through the cloudburst of 23 September 2025, when 332 mm fell in a few hours and parts of Kolkata stayed waterlogged for three days.
An online school in Kolkata removes the school run, in a city the TomTom Traffic Index 2025 ranks 29th in the world at 59 per cent congestion. Those hours go back to your child.
Your child attends live classes that record attendance, meeting CBSE's 75 per cent rule for the board exam. An afternoon or evening batch keeps coaching hours clear.
A move to Bengaluru or a posting to the Gulf changes the address and nothing else. Same school, same teacher, same batch, no new admission.
Two teachers to twenty students, so no child is carried along at the back. Six board routes, and your child can switch without applying again.
Pick the curriculum by where your child will study next. NIOS or BOSSE work for Indian colleges. Cambridge works for the UK and most other countries. The American or Australian route works for a family moving abroad. All six run live in one virtual online school, Nursery to Grade 12. Find your child's stage: Pre-Primary, Primary, Middle, Secondary or Senior Secondary.

Our online school in Kolkata teaches ages 3 to 18, in five stages. Your child is placed by age, not by the grade name on the last report card. The same year has a different name in each system. Middle School in India is Lower Secondary at Cambridge. If your child is moving from another curriculum, we read the last report card.
| Age | Indian Curriculum | Cambridge Curriculum (UK) | American Curriculum |
|---|---|---|---|
| 3 to 5 | Pre-Primary School | Early Years School | Kindergarten School |
| 5 to 10 | Primary School | Primary School | Elementary School |
| 10 to 13 | Middle School | Lower Secondary | Middle School |
| 13 to 16 | Secondary School | Upper Secondary School | High School |
| 16 to 18 | Senior Secondary | AS and A Levels | High School (Grades 11 to 12) |
Admission runs in every month of the year, so a transfer into or out of Kolkata does not cost a term. The academic team places the child from the previous school's marksheet rather than a test, and recorded sessions cover whatever the class has already been taught.
An online school in Kolkata fits a family on four counts: it removes the commute, it lets you pick the batch around music, sport or coaching, it opens international and Indian board routes from home, and it gives certified teachers, live classes and recorded progress rather than a syllabus you build yourself. Five kinds of family get the most out of it.
A child in serious football, cricket, swimming, Rabindrasangeet or classical dance keeps the school year. They do not have to choose between school and training. Three batches run every day, and every class is recorded for the days they cannot join.
A move from Salt Lake to Bengaluru, or a posting to the Gulf or Singapore, changes your address and nothing else. The same school, teacher and batch carry on. There is no fresh admission and no lost term.
A family aiming at a university abroad can take Cambridge IGCSE and A Level, the American route, or the Australian Curriculum under SCSA, and the Indian route through NIOS or BOSSE stays open alongside them. Your child studies all of it from home in Kolkata.
A child with a learning difference works to a plan written for them. Teachers trained in special education take the class, and the child stays in an ordinary class rather than a separate one. The pace is set by the child, which a class of forty cannot do.
A child in treatment or recovery keeps the school year, because the class comes to the room they are in. Every lesson is recorded for the days they cannot attend. Academic and emotional support sits alongside it.
Sit in on a live class before deciding, with a counsellor who knows the Kolkata school landscape. No obligation.

CBSE does not affiliate fully online schools anywhere in India, which is why the syllabus is CBSE-aligned while the certificate comes from NIOS or BOSSE. Both sit under the Ministry of Education, and NIOS is recognised by MHRD and UGC.
Who certifies what:
The whole week at Sunbeam World School is taught live, period by period, by a subject teacher, and recordings exist for revision rather than in place of the lesson. Attendance is taken in the live class, which is what separates this from a recorded course and what makes the attendance record worth something.
The class size at Sunbeam World School is twenty students with two teachers, a ratio of 2:20, and a quiet child gets noticed inside the lesson. The assistant subject teacher follows the lesson alongside the class teacher and picks up the child who has stopped answering. In a class of forty that child is usually missed until the report card.
A Kolkata student prepares for JEE or NEET at Sunbeam World School while staying enrolled in a school they actually attend. CBSE asks for 75 per cent attendance before the board exam and checks it by surprise inspection, so a name on a roll is a risk the family carries. Our live classes record attendance, the afternoon or evening batch leaves coaching hours clear, and the school handles board registration.
Everything you need to judge Sunbeam World School is published before you pay. The fee structure is online grade by grade, the accreditations carry numbers you can check on the issuing body's own site, the school timings list every batch, and a free demo class puts you in a live lesson with the teacher who would take your child's batch.
If you move out of Kolkata or abroad, Sunbeam World School moves with you, because the classroom is the login. Families who move to Bengaluru, or are posted to the Gulf, Singapore or the United States, keep the same teacher, the same batch and the same board route. The timetable stays on Indian Standard Time unless you ask to change batch.
If a live class fails to load during a power cut, support at Sunbeam World School is reachable from inside the learning platform through the school day, and every class is recorded, so a household that loses power rejoins and catches the lesson the same day.
Your child is kept safe at Sunbeam World School because classes are closed to registered students, so no outsider can join, and two teachers are present in every session. Chat and camera use sit under teacher control, and the class is supervised throughout rather than left to run on its own.
